Description
本発明は、錠剤印刷装置等において、供給される多数の錠剤等の物品を所定の搬送方向に沿って搬送しながら複数列に振り分けるための振分け装置に関するものである。 The present invention relates to a sorting device for sorting a plurality of supplied articles such as tablets into a plurality of rows while being transported along a predetermined transport direction in a tablet printing device or the like.
従来、医療分野において、薬剤師による調剤ミスや患者による誤服用などの医療事故を防止するために、インクジェットプリンタにより錠剤の表面にインクを噴射して印刷を行う錠剤印刷装置が知られている。 2. Description of the Related Art Conventionally, in the medical field, in order to prevent medical accidents such as dispensing errors by a pharmacist or mistaking by a patient, a tablet printing apparatus that performs printing by ejecting ink onto the surface of a tablet by an ink jet printer is known.
一般に、この錠剤印刷装置は、錠剤が供給される錠剤供給部と、錠剤を搬送する錠剤搬送部と、錠剤の表面に印刷を行う錠剤印刷部と、錠剤の印刷、割れあるいは欠け等の状態を検査する錠剤検査部と、錠剤が排出される錠剤排出部とから構成される。これによると、錠剤に対して非接触で印刷処理を行うことができる。 In general, the tablet printing apparatus includes a tablet supply unit for supplying tablets, a tablet conveyance unit for conveying tablets, a tablet printing unit for printing on the surface of tablets, and states such as tablet printing, cracking or chipping. It is comprised from the tablet inspection part to test | inspect and the tablet discharge | emission part from which a tablet is discharged | emitted. According to this, it is possible to perform the printing process in a non-contact manner on the tablet.
そして、このような錠剤印刷装置では、錠剤供給部と錠剤搬送部の間に振分け装置が配置される場合が多い。この振分け装置は、各物品を搬送するための搬送溝が搬送方向に延びる態様で複数列設けられたトラフを備え、トラフを搬送方向に振動させることにより、錠剤を所定の搬送方向に沿って搬送しながら複数列に振り分ける（例えば、特許文献１、２参照）。 In such a tablet printing apparatus, a sorting device is often disposed between the tablet supply unit and the tablet transport unit. This sorting apparatus includes troughs provided in a plurality of rows in a manner in which a conveyance groove for conveying each article extends in the conveyance direction, and conveys the tablets along a predetermined conveyance direction by vibrating the troughs in the conveyance direction. However, they are distributed into a plurality of rows (see, for example, Patent Documents 1 and 2).
しかしながら、通常、錠剤は各搬送溝において一列で搬送されるが、中には各搬送溝において装置の幅方向に２列に並んで搬送されるものがあり、そのような状態で錠剤を錠剤搬送部に受け渡してしまうと、錠剤印刷部により錠剤の表面に印刷を行うことが困難になり、錠剤印刷装置における錠剤印刷の良品率が低下するという問題があった。特に最近では、平面視が円形の錠剤のみならず、平面視が長円形、楕円形、菱形、涙形などのように外形の一辺が直線状の部分を有する異形錠と呼ばれる錠剤が増えてきており、このような異形錠は平面視が円形の錠剤に比べて、幅方向に２列に並んで搬送される場合が多かった。なお、このような問題は、錠剤のみに限られるものではなく、その他の物品にも生じるものであった。 However, tablets are usually transported in a row in each transport groove, but some tablets are transported in two rows in the width direction of the device in each transport groove, and tablets are transported in such a state. If it is delivered to the printing section, it becomes difficult to print on the surface of the tablet by the tablet printing section, and there is a problem that the yield rate of tablet printing in the tablet printing apparatus is reduced. In recent years, not only tablets with a circular shape in plan view but also tablets called odd-shaped tablets having a linear part on one side of the outer shape such as an oval shape, an ellipse, a rhombus, and a tear shape in a plan view are increasing. Such deformed tablets are often conveyed in two rows in the width direction as compared with tablets having a circular plan view. Such a problem is not limited to tablets only, but also occurs in other articles.
本発明は、上述の問題に鑑みてなされたものであって、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる振分け装置を提供することを目的とする。 The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a sorting apparatus that can easily and reliably sort articles in a row in each conveyance groove.
本発明は、上記目的を達成するために、物品を所定の搬送方向に沿って搬送しながら複数列に振り分けるための振分け装置であって、各物品を搬送するための搬送溝が搬送方向に延びる態様で複数列設けられ、前記搬送溝は、搬送方向に直交する幅方向に対して一方側または他方側に上方に傾斜する第１の溝底面と、幅方向に対して一方側または他方側に上方に傾斜する第２の溝底面とを備える谷形状に形成され、前記第２の溝底面は、少なくとも搬送方向の一部において、上方から見て搬送方向に対して前記第１の溝底面側に交差する方向に傾斜しながら延びる態様で形成されていることを特徴とする。なお、第１の溝底面および第２の溝底面について、上方に傾斜する状態には直立状態（傾斜角度９０度）も含まれる。 In order to achieve the above object, the present invention is a sorting device for sorting articles into a plurality of rows while carrying an article along a predetermined carrying direction, and a carrying groove for carrying each article extends in the carrying direction. A plurality of rows are provided in the embodiment, and the conveyance groove is formed on the first groove bottom surface inclined upward in one side or the other side with respect to the width direction orthogonal to the conveyance direction, and on one side or the other side in the width direction. The second groove bottom surface is formed in a valley shape including a second groove bottom surface that is inclined upward, and the second groove bottom surface is at least partly in the transport direction and the first groove bottom surface side with respect to the transport direction as viewed from above It is characterized by being formed in an aspect extending while being inclined in a direction intersecting with. Note that the state in which the first groove bottom surface and the second groove bottom surface are inclined upward includes an upright state (inclination angle of 90 degrees).
これによれば、物品が搬送溝で幅方向に２列に並んで搬送された場合、第２の溝底面側の物品は、第２の溝底面との間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面側の物品は、幅方向に隣接する第２の溝底面側の物品との間において小さな摩擦しか生じないため、搬送速度がほとんど低下しないことから、第２の溝底面側の物品が第１の溝底面側の錠剤よりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面側の物品が、搬送速度が相対的に遅い第２の溝底面側の物品よりも搬送方向前方に出る状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる。 According to this, when the article is conveyed in two rows in the width direction in the conveyance groove, the article on the second groove bottom surface side generates a large friction between the second groove bottom surface, On the other hand, since the article on the first groove bottom surface side generates only a small amount of friction with the article on the second groove bottom surface side adjacent in the width direction, the conveyance speed hardly decreases. The conveyance speed of the article on the groove bottom side is relatively slower than that of the tablet on the first groove bottom side. Therefore, the article on the first groove bottom surface side, which has a relatively high conveyance speed, comes out forward in the conveyance direction than the article on the second groove bottom surface side, which has a relatively low conveyance speed, and the article is conveyed. Since the articles are conveyed while being arranged in a line in the groove, the articles can be easily and reliably distributed in a line in each conveyance groove.
また、前記第２の溝底面は、上方から見て搬送方向に対して傾斜角度が１度〜６０度に形成されているのが好ましい。これによれば、第２の溝底面側の物品は、第２の溝底面との間において適度に大きな摩擦が生じることにより搬送速度が適度に低下するため、物品が当該搬送溝において一列に並びながら搬送され易くなる。 In addition, it is preferable that the second groove bottom surface is formed with an inclination angle of 1 degree to 60 degrees with respect to the transport direction when viewed from above. According to this, the articles on the second groove bottom surface side have a reasonably large friction with the second groove bottom surface, so that the conveyance speed is moderately reduced. Therefore, the articles are arranged in a line in the conveyance groove. It becomes easy to be conveyed.
また、前記第２の溝底面は、幅方向に対して傾斜角度が４５度〜１３５度に形成されているのが好ましい。これによれば、第２の溝底面との間において確実に大きな摩擦が生じることにより搬送速度が確実に低下するため、物品が当該搬送溝において一列に並びながら搬送され易くなる。 Further, it is preferable that the second groove bottom surface is formed with an inclination angle of 45 degrees to 135 degrees with respect to the width direction. According to this, since a large friction is surely generated between the bottom surface of the second groove and the transport speed is surely reduced, the articles are easily transported while being aligned in a line in the transport groove.
また、前記第２の溝底面は、上方から見て搬送方向に対して前記第１の溝底面側に交差する方向に傾斜しながら延びる部分の搬送方向下流側の端部から、上方から見て搬送方向に対して前記第１の溝底面と反対側に交差する方向に傾斜しながら延びる態様で形成されていてもよい。これによれば、第２の溝底面側の物品が、第２の溝底面との間の摩擦から解放されて早い速度で搬送されるため、搬送方向に隣り合う第２の溝底面側の物品の間に大きな隙間が生じる。このため、第１の溝底面側の物品が、第２の溝底面側の物品の間に生じた当該隙間に入りんだ状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列により一層確実に振り分けることができる。
また、前記第２の溝底面は、第１の溝底面よりも摩擦係数が大きくなるように形成されてもよい。これによれば、第２の溝底面の物品は、第２の溝底面との間においてより大きな摩擦が生じるため、物品が当該搬送溝３１０において一列に並びながら搬送され易くなる。
Further, the second groove bottom surface is viewed from above from the end portion on the downstream side in the transport direction of the portion extending while being inclined in a direction intersecting the first groove bottom surface side with respect to the transport direction when viewed from above. You may form in the aspect extended while inclining in the direction which cross | intersects the said 1st groove | channel bottom face with respect to a conveyance direction. According to this, since the article on the second groove bottom surface side is released from the friction with the second groove bottom surface and is conveyed at a high speed, the article on the second groove bottom surface side adjacent in the conveying direction. A large gap is formed between the two. For this reason, the article on the first groove bottom surface side enters the gap generated between the articles on the second groove bottom surface side, and the articles are conveyed while being aligned in a row in the conveyance groove. Therefore, the articles can be more surely distributed in one row in each conveyance groove.
In addition, the second groove bottom surface may be formed so that a friction coefficient is larger than that of the first groove bottom surface. According to this, the article on the bottom surface of the second groove is more frictioned with the bottom surface of the second groove, so that the articles are easily transported while being aligned in a row in the transport groove 310.
また、本発明は、上記振分け装置が設けられていることを特徴とする錠剤印刷装置である。 In addition, the present invention is a tablet printing device provided with the above-described sorting device.
本発明によれば、物品が搬送溝で幅方向に２列に並んで搬送された場合、第２の溝底面側の物品は、第２の溝底面との間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面側の物品は、幅方向に隣接する第２の溝底面側の物品との間において小さな摩擦しか生じないため、搬送速度がほとんど低下しないことから、第２の溝底面側の物品が第１の溝底面側の錠剤よりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面側の物品が、搬送速度が相対的に遅い第２の溝底面側の物品よりも搬送方向前方に出る状態となって、物品が当該搬送溝において一列に並びながら搬送されるため、物品を各搬送溝において一列に簡単かつ確実に振り分けることができる。 According to the present invention, when the articles are conveyed in two rows in the width direction in the conveyance groove, the article on the second groove bottom surface side generates a large friction with the second groove bottom surface. While the speed is reduced, the article on the first groove bottom surface side generates only a small amount of friction with the article on the second groove bottom surface side adjacent in the width direction. The conveyance speed of the article on the groove bottom surface side of 2 is relatively slower than the tablet on the first groove bottom surface side. Therefore, the article on the first groove bottom surface side, which has a relatively high conveyance speed, comes out forward in the conveyance direction than the article on the second groove bottom surface side, which has a relatively low conveyance speed, and the article is conveyed. Since the articles are conveyed while being arranged in a line in the groove, the articles can be easily and reliably distributed in a line in each conveyance groove.
このため、例えば本装置を錠剤印刷装置に適用した場合、錠剤供給部に供給された錠剤を錠剤搬送部に対して一列で順次受け渡すため、錠剤印刷部により錠剤の表面に所定の印刷を確実に行うことができ、ひいては錠剤印刷の良品率を向上させることが可能となる。 For this reason, for example, when this apparatus is applied to a tablet printing apparatus, the tablets supplied to the tablet supply unit are sequentially delivered to the tablet transport unit in a line, so that the tablet printing unit reliably performs predetermined printing on the surface of the tablet. Therefore, it is possible to improve the yield rate of tablet printing.

前記振分けトラフ３１は、図２に示すように、錠剤Ｔを搬送するための搬送溝３１０が搬送方向Ｘに延びる態様で設けられている。これら搬送溝３１０は、幅方向に７列設けられており、幅方向の左側（図２の上側）の３列の各搬送溝３１０（３１０Ｌ）と、幅方向の右側（図２の下側）の４列の各搬送溝３１０（３１０Ｒ）から構成される。なお、振分けトラフ３１は、上流側に平坦面３１１が形成されており、該平坦面３１１が前記搬送溝３１０の上流側端部に連続して接続されている。 As shown in FIG. 2, the distribution trough 31 is provided with a conveyance groove 310 for conveying the tablet T extending in the conveyance direction X. These conveyance grooves 310 are provided in seven rows in the width direction, each of the three rows of conveyance grooves 310 (310L) on the left side in the width direction (upper side in FIG. 2) and the right side in the width direction (lower side in FIG. 2). The four rows of each of the conveying grooves 310 (310R). The distribution trough 31 has a flat surface 311 on the upstream side, and the flat surface 311 is continuously connected to the upstream end of the conveying groove 310.

Since the tablet T is formed in an oval shape, as shown in FIG. 5, the long side direction of the tablet T (left and right direction in FIG. 8B) is along the transport direction X during transport. The description will be made on the assumption that it is conveyed. FIG. 4 shows the tablet T larger than the actual size for convenience of explanation.

Further, as shown in FIG. 3, the first groove bottom surface 310a and the second groove bottom surface 310b are gradually increased in height from the upper end portion to the lower end portion of the groove bottom surface. In addition, the first groove bottom surface 310a and the second groove bottom surface 310b are higher in height than the heights of the first groove bottom surface 310a and the second groove bottom surface 310b between the A part and the B part of the sorting trough 31. A large gradient is formed in the transport direction X. Further, the first groove bottom surface 310a and the second groove bottom surface 310b are both formed to extend in parallel to the transport direction X as shown in FIG.

That is, the first groove bottom surface 310a is formed so as to maintain an inclination angle of 30 degrees with respect to the width direction between the C portion and the D portion of the distribution trough 31, and the second groove bottom surface 310b is formed in the width direction. On the other hand, it is formed so as to maintain an inclination angle of 90 degrees. Further, as shown in FIG. 3, the first groove bottom surface 310a and the second groove bottom surface 310b have a constant height from the upper end portion to the lower end portion of the groove bottom surface.
また、振分けトラフ３１のＣ部からＤ部の間、図２および図５に示すように、幅方向の左側の１列目から３列目の搬送溝３１０Ｌにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａ側（幅方向の右側）に交差する方向に傾斜角度α（本実施形態では３度）で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０Ｒにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａ側（幅方向の左側）に交差する方向に傾斜角度α（本実施形態では３度）で傾斜しながら延びる態様で形成されている。 Further, as shown in FIGS. 2 and 5, the second groove bottom surface 310b of the conveying grooves 310L in the first to third rows on the left side in the width direction is located between the C portion and the D portion of the distribution trough 31. When viewed from the side, the first groove bottom surface 310a side (the right side in the width direction) is formed so as to extend while being inclined at an inclination angle α (3 degrees in this embodiment). On the other hand, the second groove bottom surface 310b in the conveyance grooves 310R in the first to fourth rows on the right side in the width direction is on the first groove bottom surface 310a side (left side in the width direction) with respect to the conveyance direction X as viewed from above. Is formed in such a manner that it extends while inclining at an inclination angle α (3 degrees in the present embodiment) in a direction intersecting with.
このように前記第２の溝底面３１０ｂは、上方から見て搬送方向に対して第１の溝底面３１０ａ側に交差する方向に傾斜しながら延びる態様で形成されるため、図７に示すように、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送された場合、図５に示すように、第２の溝底面３１０ｂ側の錠剤Ｔは、第２の溝底面３１０ｂとの間において大きな摩擦が生じるため、搬送速度が低下する一方、第１の溝底面３１０ａ側の錠剤は、幅方向に隣接する第２の溝底面３１０ｂ側の錠剤Ｔとの間において小さな摩擦しか生じないため、搬送速度が低下しないことから、第２の溝底面３１０ｂ側の錠剤Ｔが第１の溝底面３１０ａ側の錠剤Ｔよりも搬送速度が相対的に遅くなる。よって、搬送速度が相対的に速い第１の溝底面３１０ａ側の錠剤Ｔが、搬送速度が相対的に遅い第２の溝底面３１０ｂ側の錠剤Ｔよりも搬送方向前方に出る状態となり、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送される。 As described above, the second groove bottom surface 310b is formed in such a manner that it extends while being inclined in a direction intersecting the first groove bottom surface 310a side with respect to the transport direction when viewed from above, as shown in FIG. When the tablets T are conveyed in two rows in the width direction in the conveying groove 310, as shown in FIG. 5, the tablet T on the second groove bottom surface 310b side is between the second groove bottom surface 310b. Since a large friction occurs, the conveyance speed is reduced, while the tablet on the first groove bottom surface 310a side generates only a small friction with the tablet T on the second groove bottom surface 310b side adjacent in the width direction. Since the transport speed does not decrease, the transport speed of the tablet T on the second groove bottom surface 310b side is relatively slower than the tablet T on the first groove bottom surface 310a side. Therefore, the tablet T on the side of the first groove bottom surface 310a having a relatively high conveyance speed comes out in the state of the front of the tablet T on the side of the second groove bottom surface 310b on the side of the second groove bottom surface 310b having a relatively low conveyance speed. Are conveyed while being arranged in a line in the conveyance groove 310.
また、振分けトラフ３１の下流側のＥ部では、図４（Ｅ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度６０度で形成されている。つまり、振分けトラフ３１のＤ部からＥ部の間、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度を維持するように形成される一方、第２の溝底面３１０ｂは幅方向に対して傾斜角度が９０度から６０度にかけて次第に小さくなるように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に低くなっている。 Further, at the E portion downstream of the distribution trough 31, as shown in FIG. 4E, the first groove bottom surface 310a is formed at an inclination angle of 30 degrees with respect to the width direction, and the second groove bottom surface. 310b is formed at an inclination angle of 60 degrees with respect to the width direction. That is, the first groove bottom surface 310a is formed so as to maintain an inclination angle of 30 degrees with respect to the width direction between the D portion and the E portion of the distribution trough 31, while the second groove bottom surface 310b is formed in the width direction. On the other hand, the inclination angle is gradually reduced from 90 degrees to 60 degrees. Further, as shown in FIG. 3, the first groove bottom surface 310 a and the second groove bottom surface 310 b are gradually lowered in height from the upper end portion to the lower end portion of the groove bottom surface.
また、振分けトラフ３１のＤ部からＥ部の間、幅方向の左側の１列目から３列目の搬送溝３１０Ｌにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の左側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０Ｒにおける第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の右側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。 In addition, the second groove bottom surface 310b in the conveyance grooves 310L in the first to third rows on the left side in the width direction between the D portion and the E portion of the sorting trough 31 is the second in the conveyance direction X as viewed from above. It is formed in such a manner that it extends while being inclined at an inclination angle of 25 degrees in a direction crossing the opposite side (left side in the width direction) of one groove bottom surface 310a. On the other hand, the second groove bottom surface 310b in the conveyance grooves 310R in the first to fourth rows on the right side in the width direction is opposite to the first groove bottom surface 310a with respect to the conveyance direction X as viewed from above (in the width direction). It is formed in such a manner that it extends while inclining at an inclination angle of 25 degrees in a direction intersecting the right side).
また、振分けトラフ３１の下流側のＦ部では、図４（Ｆ）に示すように、第１の溝底面３１０ａは傾斜角度３０度で形成されるとともに、第２の溝底面３１０ｂは傾斜角度３０度で形成されている。つまり、振分けトラフ３１のＥ部からＦ部の間、第１の溝底面３１０ａは傾斜角度３０度を維持するように形成される一方、第２の溝底面３１０ｂは傾斜角度が６０度から３０度にかけて次第に小さくなるように形成されている。また、第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さが次第に低くなっている。 Further, in the F portion on the downstream side of the distribution trough 31, as shown in FIG. 4F, the first groove bottom surface 310a is formed at an inclination angle of 30 degrees, and the second groove bottom surface 310b is inclined at an inclination angle of 30 degrees. Formed in degrees. That is, the first groove bottom surface 310a is formed to maintain an inclination angle of 30 degrees between the E portion and the F portion of the distribution trough 31, while the second groove bottom surface 310b has an inclination angle of 60 degrees to 30 degrees. It is formed so as to gradually become smaller. Further, as shown in FIG. 3, the first groove bottom surface 310 a and the second groove bottom surface 310 b are gradually lowered in height from the upper end portion to the lower end portion of the groove bottom surface.
また、振分けトラフ３１のＥ部からＦ部の間、幅方向の左側の１列目から３列目の搬送溝３１０における第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の左側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０における第２の溝底面３１０ｂは、上方から見て搬送方向Ｘに対して第１の溝底面３１０ａと反対側（幅方向の右側）に交差する方向に傾斜角度２５度で傾斜しながら延びる態様で形成されている。 In addition, the second groove bottom surface 310b of the conveying grooves 310 in the first to third rows on the left side in the width direction between the E portion and the F portion of the sorting trough 31 is It is formed in such a manner that it extends while being inclined at an inclination angle of 25 degrees in a direction crossing the opposite side (left side in the width direction) of one groove bottom surface 310a. On the other hand, the second groove bottom surface 310b in the first to fourth conveyance grooves 310 on the right side in the width direction is opposite to the first groove bottom surface 310a with respect to the conveyance direction X as viewed from above (in the width direction). It is formed in such a manner that it extends while inclining at an inclination angle of 25 degrees in a direction intersecting the right side).
このように、振分けトラフ３１のＤ〜Ｆ部において、前記第２の溝底面３１０ｂは、傾斜角度が搬送方向Ｘの上流側において第１の溝底面３１０ａの傾斜角度よりも大きく形成され、搬送方向Ｘの下流側に向かうにつれて次第に小さくなるように形成されている。このため、仮に錠剤Ｔが起立状態で供給された場合でも、振分けトラフ３１のＤ〜Ｆ部において、第１の溝底面３１０ａから第２の溝底面３１０ｂに向けて起立状態から横倒状態に次第に移行しながら搬送される。 As described above, in the portions D to F of the distribution trough 31, the second groove bottom surface 310b is formed with an inclination angle larger than the inclination angle of the first groove bottom surface 310a on the upstream side in the conveyance direction X, and in the conveyance direction. It forms so that it may become small gradually as it goes to the downstream of X. For this reason, even if the tablet T is supplied in an upright state, in the D to F portions of the sorting trough 31, from the first groove bottom surface 310a toward the second groove bottom surface 310b, the tablet T gradually changes from the standing state to the sideways state. It is transported while moving.
また、前記第２の溝底面３１０ｂは、上方から見て搬送方向に対して前記第１の溝底面３１０ａ側に交差する方向に傾斜しながら延びる部分（Ｃ部〜Ｄ部）の搬送方向下流側の端部（Ｃ部）から、上方から見て搬送方向に対して前記第１の溝底面３１０ａと反対側に交差する方向に傾斜しながら延びる態様で形成されている。このため、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送され、振分けトラフ３１のＣ部〜Ｄ部においても２列に並んだ状態が解消されなかった錠剤Ｔが少数ながら存在していた場合、図６に示すように、第２の溝底面側の物品Ｔａ、Ｔｂが、第２の溝底面３１０ｂとの間の摩擦から解放されて早い速度で搬送されるため、搬送方向に隣り合う第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に大きな隙間が生じる。このため、第１の溝底面３１０ａ側の錠剤Ｔｃが、第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に生じた当該隙間に入りんだ状態となって、状態Ｔａ、Ｔｂ、Ｔｃが当該搬送溝３１０において一列に並びながら搬送されるため、錠剤Ｔを各搬送溝３１０において一列により一層確実に振り分けることができる。 Further, the second groove bottom surface 310b is downstream in the conveyance direction of a portion (C part to D part) extending while being inclined in a direction intersecting the first groove bottom surface 310a side with respect to the conveyance direction when viewed from above. From the end portion (C portion), the first groove bottom surface 310a is inclined while extending in a direction crossing the opposite side of the first groove bottom surface 310a with respect to the transport direction when viewed from above. For this reason, there are a small number of tablets T in which the tablets T are transported in two rows in the width direction in the transport groove 310 and the state of being aligned in two rows is not eliminated in the C part to D part of the sorting trough 31. 6, the articles Ta and Tb on the second groove bottom surface side are released from the friction with the second groove bottom surface 310b and are conveyed at a high speed as shown in FIG. A large gap is formed between the tablets Ta and Tb on the adjacent second groove bottom surface 310b side. For this reason, the tablet Tc on the first groove bottom surface 310a side enters the gap formed between the tablets Ta and Tb on the second groove bottom surface 310b side, and the states Ta, Tb, and Tc are Since it is conveyed while being arranged in a line in the conveyance groove 310, the tablets T can be more reliably distributed in a line in each of the conveyance grooves 310.
また、振分けトラフ３１の最下流側のＦ部〜Ｇ部（Ｆ部を除く）の間では、図４（Ｇ）に示すように、第１の溝底面３１０ａは幅方向に対して傾斜角度３０度の一定角度で形成されるとともに、第２の溝底面３１０ｂは幅方向に対して傾斜角度３０度の一定角度で形成され、両側に直立状態の壁部３１０ｃが形成されている。また、振分けトラフ３１のＦ部からＧ部の間における第１の溝底面３１０ａおよび第２の溝底面３１０ｂは、図３に示すように、溝底面の上端部から下端部までの高さは一定であるが、壁部３１０ｃは、高さが次第に高くなっている。 Further, between the F portion to G portion (excluding the F portion) on the most downstream side of the distribution trough 31, as shown in FIG. 4G, the first groove bottom surface 310a has an inclination angle of 30 with respect to the width direction. The second groove bottom surface 310b is formed at a constant angle of an inclination angle of 30 degrees with respect to the width direction, and the upright wall portions 310c are formed on both sides. Further, the first groove bottom surface 310a and the second groove bottom surface 310b between the F portion and the G portion of the distribution trough 31 have a constant height from the upper end portion to the lower end portion of the groove bottom surface as shown in FIG. However, the height of the wall portion 310c is gradually increased.
また、幅方向の左側の１列目から３列目の搬送溝３１０における壁部３１０ｃは、上方から見て搬送方向Ｘに対して幅方向の右側に交差する方向に傾斜しながら延びる態様で形成されている。一方、幅方向の右側の１列目から４列目の搬送溝３１０における壁部３１０ｃは、上方から見て搬送方向Ｘに対して幅方向の左側に交差する方向に傾斜しながら延びる態様で形成されている。これにより錠剤Ｔは次第に幅方向中央部に向けて互いの距離を縮めながら搬送されていき、整列トラフ３２の搬送溝に受け渡される。 Further, the wall portion 310c in the conveyance grooves 310 in the first to third rows on the left side in the width direction is formed in a manner extending while being inclined in a direction intersecting the right side in the width direction with respect to the conveyance direction X when viewed from above. Has been. On the other hand, the wall portion 310c of the conveyance grooves 310 in the first to fourth rows on the right side in the width direction is formed so as to extend while inclining in a direction intersecting the left side in the width direction with respect to the conveyance direction X when viewed from above. Has been. As a result, the tablets T are gradually conveyed toward the center in the width direction while reducing the distance between them, and are delivered to the conveying groove of the alignment trough 32.
次に、錠剤Ｔの搬送される過程について説明する。なお、実際には多数の錠剤Ｔが搬送されるが、説明の便宜上、一の錠剤Ｔが幅方向の左側の２列目の搬送溝３１０に搬送される場合について説明する。 Next, a process of transporting the tablet T will be described. Although a large number of tablets T are actually transported, for convenience of explanation, a case where one tablet T is transported to the transport groove 310 in the second row on the left side in the width direction will be described.
まず、錠剤Ｔが水平な横倒状態で供給された場合、図４（Ａ）に示すように、錠剤Ｔは、振分けトラフ３１の平坦面３１１において水平な横倒状態で搬送されたあと、図４（Ｂ）に示すように、振分けトラフ３１のＡ部〜Ｂ部の間において、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度０度〜１０度の横倒状態で搬送される。 First, when the tablet T is supplied in a horizontal sideways state, as shown in FIG. 4A, the tablet T is transported in a horizontal sideways state on the flat surface 311 of the sorting trough 31, 4 (B), between the A and B portions of the sorting trough 31, one surface T1 is supported by the first groove bottom surface 310a, and the circumferential surface T2 is supported by the second groove bottom surface 310b. It is conveyed in a sideways state with a tilt angle of 0 degrees to 10 degrees.
そして、振分けトラフ３１のＢ部〜Ｃ部において、図４（Ｂ）〜図４（Ｃ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度１０度〜３０度の横倒状態で搬送される。 And in B part-C part of distribution trough 31, as shown in Drawing 4 (B)-Drawing 4 (C), as for tablet T, one surface T1 is supported by the 1st slot bottom face 310a, and tablet The circumferential surface T2 of T is conveyed in a sideways state with an inclination angle of 10 degrees to 30 degrees supported by the second groove bottom surface 310b.
そして、振分けトラフ３１のＣ部〜Ｄ部において、図４（Ｃ）〜図４（Ｄ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度３０度の横倒状態で搬送される。 And in C part-D part of the distribution trough 31, as shown to FIG.4 (C)-FIG.4 (D), one surface T1 is supported by the 1st groove bottom face 310a, and tablet T The circumferential surface T2 of T is conveyed in a sideways state with an inclination angle of 30 degrees supported by the second groove bottom surface 310b.
このとき、図７に示すように、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送された場合、図５に示すように、第２の溝底面３１０ｂ側の錠剤Ｔが第１の溝底面３１０ａ側の錠剤Ｔよりも搬送速度が相対的に遅くなるため、搬送速度が相対的に速い第１の溝底面３１０ａ側の錠剤Ｔが、搬送速度が相対的に遅い第２の溝底面３１０ｂ側の錠剤Ｔよりも搬送方向前方に出る状態となり、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送される。 At this time, as shown in FIG. 7, when the tablets T are transported in two rows in the width direction in the transport groove 310, the tablet T on the second groove bottom surface 310 b side is the first tablet T as shown in FIG. 5. Since the transport speed is relatively slower than the tablet T on the groove bottom surface 310a side, the tablet T on the first groove bottom surface 310a side with the relatively fast transport speed is the second groove with the relatively slow transport speed. The tablet T comes out forward in the transport direction from the tablet T on the bottom surface 310 b side, and the tablets T are transported while being aligned in a line in the transport groove 310.
そして、振分けトラフ３１のＤ部〜Ｆ部において、図４（Ｄ）〜図４（Ｆ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａに支承され、かつ錠剤Ｔの周面Ｔ２が第２の溝底面３１０ｂに支承された傾斜角度３０度の横倒状態で搬送される。 And in D part-F part of distribution trough 31, as shown in Drawing 4 (D)-Drawing 4 (F), as for tablet T, one surface T1 is supported by the 1st slot bottom face 310a, and tablet The circumferential surface T2 of T is conveyed in a sideways state with an inclination angle of 30 degrees supported by the second groove bottom surface 310b.
このとき、錠剤Ｔが搬送溝３１０で幅方向に２列に並んで搬送され、振分けトラフ３１のＣ部〜Ｄ部においても２列に並んだ状態が解消されなかった錠剤Ｔが少数ながら存在していた場合、図６に示すように、第１の溝底面３１０ａ側の錠剤Ｔｃが、第２の溝底面３１０ｂ側の錠剤Ｔａ、Ｔｂの間に生じた隙間に入りんだ状態となって、状態Ｔａ、Ｔｂ、Ｔｃが当該搬送溝３１０において一列に並びながら搬送される。 At this time, the tablets T are transported in two rows in the width direction in the transport groove 310, and there are a small number of tablets T in which the state of being aligned in two rows is not eliminated in the C part to D part of the sorting trough 31. If it is, as shown in FIG. 6, the tablet Tc on the first groove bottom surface 310a side enters the gap generated between the tablets Ta, Tb on the second groove bottom surface 310b side, The states Ta, Tb, and Tc are transported while being aligned in a row in the transport groove 310.
そして、振分けトラフ３１のＦ部〜Ｇ部の間（Ｆ部を除く）において、図４（Ｇ）に示すように、錠剤Ｔは、一方の表面Ｔ１が第１の溝底面３１０ａと第２の溝底面３１０ｂに支承されたほぼ水平の横倒状態で搬送されていき、整列トラフ３２の搬送溝３１０に受け渡される。 And between F part-G part (except F part) of distribution trough 31, as shown in Drawing 4 (G), as for tablet T, one surface T1 is the 1st slot bottom 310a and the 2nd It is transported in a substantially horizontal sideways state supported by the groove bottom surface 310 b and transferred to the transport groove 310 of the alignment trough 32.
なお、本実施形態では、錠剤Ｔとして平面視が長円形のものを搬送したが、一対の表面Ｔ１と周面Ｔ２を有する平面視が円形、楕円形、菱形、涙形など、その他の形状のものを搬送してもよい。要は、錠剤Ｔの形状が起立状態と横倒状態の両状態が可能なものであれば、どのような形状の錠剤Ｔを搬送してもよい。 In this embodiment, the tablet T is conveyed in an oblong shape in plan view, but the plan view having a pair of surfaces T1 and a peripheral surface T2 has other shapes such as a circle, an ellipse, a rhombus, and a teardrop. Things may be conveyed. In short, as long as the shape of the tablet T can be in both the standing state and the sideways state, the tablet T having any shape may be conveyed.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度が３度に形成されるものとしたが、その他の傾斜角度であってもよい。ただ、２列に並んで搬送された錠剤Ｔを確実に１列に移行させるため、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度は１度〜６０度に形成されるのが好ましい。このように第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を１度以上としたのは、第２の溝底面３１０ｂにより錠剤Ｔに対して摩擦を生じさせるためである。また、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を６０度以下としたのは、第２の溝底面３１０ｂが錠剤Ｔの搬送の障害となることを防止するためである。 Moreover, although the inclination angle with respect to the conveyance direction X of the 2nd groove bottom face 310b shall be formed in 3 degrees between the C parts -D part of the distribution trough 31, other inclination angles may be sufficient. However, it is preferable that the inclination angle of the second groove bottom surface 310b with respect to the transport direction X is 1 to 60 degrees in order to reliably transfer the tablets T transported in two lines to one line. The reason why the inclination angle of the second groove bottom surface 310b with respect to the conveying direction X is set to 1 degree or more is to cause friction with respect to the tablet T by the second groove bottom surface 310b. The reason why the inclination angle of the second groove bottom surface 310b with respect to the conveyance direction X is 60 degrees or less is to prevent the second groove bottom surface 310b from obstructing the conveyance of the tablet T.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、第２の溝底面３１０ｂの幅方向に対する傾斜角度を９０度としたが、その他の傾斜角度であってもよい。ただ、２列に並んで搬送された錠剤Ｔを確実に１列に移行させるため、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度は４５度〜１３５度（すなわち幅方向一方側に３５度以上、幅方向他方側に３５度以上）に形成されるのが好ましい。このように第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を４５度〜１３５度としたのは、第２の溝底面３１０ｂにより錠剤Ｔに対して摩擦を確実に生じさせるためである。 In addition, although the inclination angle with respect to the width direction of the second groove bottom surface 310b is 90 degrees between the C part and the D part of the distribution trough 31, other inclination angles may be used. However, in order to reliably transfer the tablets T conveyed in two rows to one row, the inclination angle of the second groove bottom surface 310b with respect to the conveyance direction X is 45 ° to 135 ° (that is, 35 ° to one side in the width direction). As described above, it is preferably formed at 35 ° or more on the other side in the width direction. The reason why the inclination angle of the second groove bottom surface 310b with respect to the conveying direction X is set to 45 degrees to 135 degrees is to cause friction to the tablet T by the second groove bottom surface 310b.
また、振分けトラフ３１のＣ部〜Ｄ部の間において、前記第２の溝底面３１０ｂは、第１の溝底面３１０ａよりも摩擦係数が大きくなるように形成されてもよい。例えば、第２の溝底面３１０ａの表面にゴム素材などの摩擦係数が大きい部材を展着したり、第２の溝底面３１０ａの表面に細かい凹凸を形成することにより表面を粗くすることが挙げられる。これによれば、第２の溝底面３１０ｂ側の錠剤Ｔは、第２の溝底面３１０ｂとの間においてより大きな摩擦が生じるため、錠剤Ｔが当該搬送溝３１０において一列に並びながら搬送され易くなる。 Further, the second groove bottom surface 310b may be formed between the C portion and the D portion of the distribution trough 31 so that the friction coefficient is larger than that of the first groove bottom surface 310a. For example, the surface of the second groove bottom surface 310a may be roughened by spreading a member having a large friction coefficient such as a rubber material or by forming fine irregularities on the surface of the second groove bottom surface 310a. . According to this, since the tablet T on the second groove bottom surface 310b side has a larger friction with the second groove bottom surface 310b, the tablets T are easily transported while being aligned in the transport groove 310. .
また、搬送トラフ３１のＤ部〜Ｆ部の間において、第２の溝底面３１０ｂの搬送方向Ｘに対する傾斜角度を２５度としたが、その他の傾斜角度であってもよい。 Moreover, although the inclination angle with respect to the conveyance direction X of the 2nd groove bottom face 310b was 25 degree | times between D part-F part of the conveyance trough 31, other inclination angles may be sufficient.
また、本発明に係る振分け装置３を錠剤を搬送する機能を有する錠剤印刷装置１に適用した場合について説明したが、その他の物品を搬送する機能を有する装置に適用してもよい。 Moreover, although the case where the distribution apparatus 3 according to the present invention is applied to the tablet printing apparatus 1 having a function of conveying tablets has been described, the distribution apparatus 3 may be applied to an apparatus having a function of conveying other articles.
以上、図面を参照して本発明の実施形態を説明したが、本発明は、図示した実施形態のものに限定されない。図示された実施形態に対して、本発明と同一の範囲内において、あるいは均等の範囲内において、種々の修正や変形を加えることが可能である。 As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure.
